Intel Atom Z2520 vs Intel Xeon D-1533N

In this CPU comparison, we compare the Intel Atom Z2520 and the Intel Xeon D-1533N and use benchmarks to check which processor is faster.

We compare the Intel Atom Z2520 2 core processor released in Q2/2013 with the Intel Xeon D-1533N which has 6 CPU cores and was introduced in Q3/2017.

The Intel Atom Z2520 is a 2 core processor with a clock frequency of 1.20 GHz. The processor can compute 4 threads at the same time. The Intel Xeon D-1533N clocks with 2.10 GHz (2.70 GHz), has 6 CPU cores and can calculate 12 threads in parallel.

The performance values of the processor's AI unit. The isolated NPU performance is specified here, the total AI performance (NPU+CPU+iGPU) can be higher. Processors with support for artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors.

Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

Up to 2 GB of memory in a maximum of 2 memory channels is supported by the Intel Atom Z2520, while the Intel Xeon D-1533N supports a maximum of 128 GB of memory with a maximum memory bandwidth of 38.4 GB/s enabled.

The Intel Atom Z2520 has a TDP of --. The TDP of the Intel Xeon D-1533N is 45 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Atom Z2520 has 1.00 MB cache and is manufactured in 32 nm. The cache of Intel Xeon D-1533N is at 9.00 MB. The processor is manufactured in 14 nm.
